people who may be exposed to hepatitis A through their job – this includes sewage workers, staff of institutions where levels of personal hygiene may be poor (such as a homeless shelter) and people working with monkeys, apes and gorillas

Contact your GP surgery if you think you should have the hepatitis A vaccine or you're not sure whether you need it.

Types of hepatitis A vaccine

Talk to your GP about which vaccine is most suitable for you. All three types are usually available for free on the NHS.

If you've travelling abroad, try to plan your vaccinations in advance. They should ideally be started at least two or three weeks before you leave, although some can be given up to the day of your departure if necessary.

Extra doses of the vaccine are often recommended after 6-12 months if you need long-term protection.
